Application filed hotelier 25, 1918. Serial Ito. 559,643.

To all whom. it may concern Be it known that L Moshe Voinnnr lim- DELL, 2L citizen of the United States, residing at Harvey, in the county of Cook and State of Illinois, have invented certain new uudfiuseful improvements in Motor-Vehicle Frames, oi which the following is e. specifie'ati'on.

This invention relates to frame construction designed primarily for motor propelled vehicles, such as trucks, sweeping machines, or other self propelled vehicles designed to carry heavy loads of material or machinery.

The primary object of the invention is to provide a frame constri'lction that will not only develop high cs1. viig capacity upon at relatively long wheel oose but great strength and rigidity under stresses incident to iongitudinel thrust transmitted from the rear area which carries the driving; wheels to the forward area, which carries the steering Wheels, and that. will also be capable of resisting torsionai stresses due to uneven surfaces upon which the front and remwheels may rest, and transverse stresses which develop from the shocks and jars of uneven roadbed over which the vehicle may travel.

A secondary object of the invention is to develop and maintain the conditions shove outlined in a. vehicle frame. which has its transverse dimension materially reduced. near its forward or steeringend as by developinp; definite offsets or deflections in its main side rails.

The invention will he more fully understood by reference to the accompanying drn wings, in which Figures 1, 2, and 3, are. respectively, a side elevation, plan View, and transverse section in e vertical plane immediately forward of the receptacle of Figs. 1 2 of u :i'iotor propelled vehicle embodying a frame in which the several. features of the present invention are incorporated; and

t is u perspective view of the principal members of the frume and their trussiug elements.

he present invention is "illustrated in "(1 motor vehicle designi-zd particularly for a. power-driven pick-up sweeper which forms the subject-matter of an appliention tiled by be me on July 24-, 1.918, (Serial No. Qt-GABZ'), and one of the clements o l which is s hero like structure or receptacle it which serves as a. sweepings receptacle in that n nizetion but which here inchuied us typical ns 51 result oil its box-like construction projecting between and secured to members of the frame construction herein claimed, as will hereinafter appear.

Utilizing, for convenience in comparison, the reference characters of my aforesaid co-pendin application so for as corresponding parts are found in the present application, F represents the main side rails of a chassis or motor vehicle frame, which are deflected inwardly at F to develop :1 front end F of reduced. transverse dimension, to receive the front steering and supporting wheels H.
